I have uploaded a new release of the microtek2 backend to
ftp://ftp.muc.de/people/bernds/mtek2/microtek2-pre0.6.270399.tar.gz .
Most important changes:
- This version addresses the problem with transposed colors on some
models with Firmware-Version 1.x (for example the X6, X6EL, Phantom 636).
The problem was/is: For a 24-bit color scan the bytes per scanline (bpl)
should be 3 * pixels per line (ppl) + 1, if the number of pixels per line
is odd, but it is actually bpl=3 * ppl + 3. This new version assumes, that
the image data starts at the "beginning of the scanline + 3 bytes", whereas
previous versions assumed "beginning of scanline + 2 bytes".
However, there are apparently people, who never experienced transposed
colors. This possibly means, that different models (different FW-versions)
handle these things different. To include the fix for all models I need
to know, which models with which FW-version have this problem. So, if
you have this problem, please send me a mail with the model name, the
FW-version and, if possible, the model code. The model_code is printed
to stderr, if 'option dump 1' is set in the microtek2.conf file, and
the FW-revision is printed with 'cat /proc/scsi/scsi' (at least on Linux).
This new release fixes the problem for devices with FW-revision 1.20 only.
Note: This is not the problem with the random noise scattered over the image
after one successful color scan, but the latter should be fixed, too,
for all FW versions known to me.
- I have included some preliminary support for a ScanMaker V6USL (really USL,
not USB). Up to now I have heard from one user, who uses this model on
an SGI machine. This user has a problem, but I assume that this problem
is SCSI related. If anybody has such a model, you could give it a try,
and tell me what happens. This model uses a data format, that appears
for the first time, so the code is partially untested.
